Exception on bound datatable action

hispeedsurfer.hispeedsurfer.gmx.net Jun 5, 2008 10:01 AM

Hi,

I have a datatable bound to a backing bean. The table is shown as expected.
And I have a action, but when I call this action the following exception is thrown

javax.el.ELException: /userExport.xhtml @21,105 binding="#{userExport.actionTable}": Error writing 'actionTable' on type org.domain.dataTableBinding.session.UserExport_$$_javassist_1

with h:dataTable the same error is thrown.
Is this a bug or what I have to change?

Checked with richfaces 3.1.5.GA and Seam 2.0.2.SP1
If needed I can send a example war file.

Thanks

What is the FacesMessages imported as (seam or jsf)?

It's Seam import. When i remove FacesMessages the excpetion is the same with EntityManager

Caused by: org.jboss.seam.RequiredException: @In attribute requires non-null value: userExport.entityManager

Aah, now I read your post ;-) Component binding. Try to see if this is relevant

Hi Nicklas,

I have no AJAX Request or concurrent calls in my case. The exception appears also with a dummy action (empty method).

I can send you an example war file with sources and you can see if desired.

No, not really ;-) But is the issue related to binding of the table?

Yes, when the table is created in 'normal' way no exception is thrown.

Oops, off by one in link. I tried referring to 7.10 Conversational components and JSF component bindings
